What are the different motions of the Earth?

Question

i need ur help............ plzzzzzzz........ thank u!

Answer 1

The motions are relative not absolute. If they were absolute we could not specify them since we would have no reference. Thus relative to the earth's axis, the earth rotates once every 24 hours. Relative to the sun it rotates once a year (about a different directional axis) and simultaneously it travels in an approximately elliptic path around the sun.

The sun with the earth is part of our galaxy which is rotating too about a center which may be a black-hole. Thus the path of the earth being carried by the solar system has an additional circular path and a rotational motion too.  

Our galaxy is one of many whose motion appears to be accelerating outward from a center which was once the origin of the big-bang. As far as I know this kind of motion has no rotational component, but it applies to the solar system and to our planet too.

Answer 2

Rotation-the turning of the earth around its axis

Revolution-the orbiting around the sun

Precession-the slow "wobble" of the north end of the earth's axis
